Balch Crater, a rifted crater on Venus

Magellan radar image of Balch Crater, Venus, originally designated
Somerville Crater. This crater is one of the few examples of tectonically
modified craters seen on Venus. The absence of such craters indicates
a possible cessation of tectonic deformation on Venus at some point
in history. Balch is located at 30 N,283 W in Devana Chasma, Central
Beta Regio. The crater was originally 37 km in diameter. North is
up.
